Abstract

Un moteur électrostatique comprend un rotor cylindrique et un stator. Des électrodes sont disposées sur une surface cylindrique intérieure du stator. Des électrets et/ou des électrodes électriquement conductrices sont disposés sur le rotor cylindrique et un fluide diélectrique remplit l'espace entre le rotor et le stator pour empêcher la décharge des électrets. Un masque est utilisé pour charger des parties d'un cylindre d'électret ou d'une autre surface incurvée.
